Her reporting gives a great overview of how prison gerrymandering dismantles our democracy’s bedrock principle of “one person, one vote” in Oklahoma.

After finishing up work at the airplane manufacturing plant where Robert Karr has worked for more than three decades, the McAlester city councilman drives his pickup truck around the town’s 4th ward. …

The Oklahoma State Penitentiary sits in Karr’s ward. But it’s not the only prison here. The Jackie Brannon Correctional Center is another block away. And those prisoners — all 1,500 or so — are technically Karr’’s constituents.

It might not be such a big deal in local politics, but Karr worries about the implications on a larger scale.
